This mill is the main equipment of cement plant for drying and grinding coal. It consists of feeding device, main bearing, rotating part, driving part, discharging assembly, high-pressure starting device and lubrication system. Raw coal is feeding into the mill via the feeding device and hot air goes into the shell through air inlet pipe. As the shell rotates, the coal does heat interchange with the hot air and is crushed and pulverized. At the same time, fine powder is carried out of the mill via discharging assembly by the hot air. The mill has a feature of reasonable construction, high pulverizing efficiency and is the perfect equipment for processing coal powder.
